I have following three button in a Linear Layout with width fill_parent.
How can I set the width of these buttons to equally cover the whole screen area?
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnReplyMessage"
android:gravity="left"
android:text="Reply"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnMarkAsUnread"
android:gravity="left"
android:text="Mark as unread"
/>
<ImageButton
android:id="#+id/btnDeleteMessage"
android:src="#drawable/imgsearch"
android:gravity="right"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
/>
Give all buttons the following properties
android:layout_width="fill_parent"
android:layout_weight="1"
fill_parent tells them to consume as much width as possible, and weight determines how that width shall be distributed, when more than one control are competing for the same space. (Try playing around with different values of weight for each button to see how that works)
You should just specify these attributes for each button:
android:layout_width="fill_parent"
android:layout_weight="1"
So it should be something like that:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
you can use following code:
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"/>
You must to do 0dp in width on every button.

I need to set two buttons side by side... I have used linearlayout for it... I have given each button to 0.5 layout_weight as i want each one to take equal space..I also make button to take equal height. The problem i am facing that left button will slide down if i give right button to match its height.
<LinearLayout
android:id="#+id/buttonLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/botomMarginTextView"
android:orientation="horizontal" >
<Button
android:id="#+id/id1"
android:layout_width="0dp"
android:layout_height="60dp"
android:layout_marginLeft="20dp"
android:layout_weight="0.5"
android:background="#drawable/button_back"
android:text="#string/name1" />
<Button
android:id="#+id/id2"
android:layout_width="0dp"
android:layout_height="60dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="20dp"
android:layout_weight="0.5"
android:background="#drawable/button_back"
android:text="#string/name2" />
</LinearLayout>
Edit :
Please give left button longer text and right button smaller
text..otherwise it is producing right layout
I am using #android:style/Theme.Black.NoTitleBar.Fullscreen . If i am going with normal theme then it is working fine
Now how to make this button keep side by side and also to make them of equal height?
To android:layout_height attribute of LinearLayout, give value of 60dp
android:layout_height="60dp"
and to android:layout_height attribute of both Button, give value of match_parent
android:layout_height="match_parent"
So, updated XML snippet will be
<LinearLayout
android:id="#+id/buttonLayout"
android:layout_width="fill_parent"
android:layout_height="60dp"
android:layout_below="#id/botomMarginTextView"
android:orientation="horizontal" >
<Button
android:id="#+id/id1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginLeft="20dp"
android:layout_weight="0.5"
android:background="#drawable/button_back"
android:text="#string/name1" />
<Button
android:id="#+id/id2"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="20dp"
android:layout_weight="0.5"
android:background="#drawable/button_back"
android:text="#string/name2" />
</LinearLayout>
I'm trying to set up an xml layout to be used for a row in a ListView. The layout consists of a root LinearLayout with a child RelativeLayout containing two ImageViews (one anchored to the other's bottom/right corner) and a child vertical LinearLayout containing two TextViews. I want each row in the listview to have the same width and height, despite the size of the content in the subviews. I realize I cannot use wrap_content which will size the views based on their content, but I'm unclear on what I should use to accomplish a uniform width/height. I tried using fixed dp values, but that just made it even worse. I've attached two screenshots. The first one, from the iOS version, shows how it should look, while the second one shows how it looks on the Android version with the following layout. As a said, I know what's wrong (the wrap_content attributes), but how do I change it to size correctly? Thanks in advance!
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<RelativeLayout

android:layout_height="wrap_content"
android:id="#+id/campaign_thumbnail_container" >
<ImageView

android:layout_height="wrap_content"

<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/campaign_thumbnail"
android:layout_alignRight="#id/campaign_thumbnail"
android:src="#drawable/new1" />
</RelativeLayout>
<LinearLayout
android:id="#+id/campaign_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/word_bar"
android:orientation="vertical" >
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/campaign_footer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
EDIT - According to comments below:
One general thing: To size elements in a LinearLayout uniformly, you need to do two things:
Use a equal android:layout_weight for each element
Make the width or height (whatever has to be uniquely sized) ="0dip"
This is, because the weight factor is only used to fill the rest of the available space. First all elements are placed using their weight/height, then the still available space is calculated and distributed by weight to each element.
EDIT-end
Now, let me create the layouts step by step.
First, this would be your layout of one entry without the "new campaign" indication.
<!-- Type 1: Picture left, text right. half-half size. Picture resized to fit -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:scaleType="fitCenter"
android:src="#android:drawable/ic_menu_camera" />
<TextView
android:id="#+id/textView1"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:text="Your Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
You get a warning, because the LinearLayout itself has a weight. That is necessary, to give all list entries the same height.
Here's type 2:
<!-- Type 2: Picture right, text left. half-half size. Picture resized to fit -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:orientation="horizontal" >
<TextView
android:id="#+id/textView2"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:text="Your Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:scaleType="fitCenter"
android:src="#android:drawable/ic_menu_camera" />
</LinearLayout>
(Where's my "That was easy!" button?)
And Type 3. Even easier:
<!-- Type 3: Picture full width. Picture resized to fit -->
<ImageView
android:id="#+id/imageView2"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:scaleType="fitCenter"
android:src="#android:drawable/ic_menu_camera" />
Now the final thing. Put these three layouts in separate XML-files and include them into a wrapping RelativeLayout.
<!-- Finally overlay the entry with a new indication -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1" >
<ImageView
android:id="#+id/newIndication"
android:layout_width="24dip"
android:layout_height="24dip"
android:layout_alignRight="#+id/entry1"
android:layout_alignBottom="#+id/entry1"
android:scaleType="fitCenter"
android:src="#android:drawable/ic_input_add" />
<include
layout="#layout/type1entry"
android:id="#+id/entry1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Note the include. I've put the Type1 LinearLayout in its own XML file named "type1entry". By giving this a new id with #+id/entry1 I can access this entry explicitely in the Activity. Also, I've given the indicator a size of 24dip in square. Change that to your image accordingly.
I've checked the layouts in Eclipse and they did look as I expected them.
Do you need to use a relative layout?
If not, use linearLayout with weights like this.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:id="#+id/campaign_thumbnail_container"
android:weightSum="100" >
<ImageView
android:id="#+id/campaign_thumbnail"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="50"
android:scaleType="fitCenter"
/>
<ImageView
android:id="#+id/campaign_mark_new"
android:layout_width="0dip"
android:layout_height="match_parent"
android:src="#drawable/new1"
android:layout_weight=50
android:scaleType="fitCenter" />
</LinearLayout>
This is untested, but similar solutions like this have worked for me in the past.
I have a TextView and Button in my program and I cannot get the size of the Button and the TextView to be the same. How can I do this?
<LinearLayout
android:layout_width="match_parent"
android:layout_height="67dp"
android:background="#999999"
android:gravity="center"
>
<Button
android:id="#+id/button1"
android:layout_width="130dp"
android:layout_height="60dp"
android:text="Button" />
<TextView
android:id="#+id/textView1"
android:layout_width="130dp"
android:layout_height="60dp"
android:background="#ffffff" android:textColor="#000000"
android:textSize="24dp" android:textStyle="bold"
android:gravity="center"
android:text="0.0" />
</LinearLayout>
Actually, they both have the same size, but the Button uses an image as a background and it seems it has some margins.
To test this, override the background of button with a color and see they are the same size:
android:background="#0F0"
So, the solution would be to provide a custom background for your button, or adapt the TextView to match the Buttons' width and height, minus the margins of Button, which personnaly I don't think is the best approach.
When I want multiple controls to have the same size what i generally do is put them in a TableLayout.
In your case, i'd put a TableLayout inside the linear layout and put the button and textview inside a TableRow, set the weightsum for the TableRow to 2 and set the weights of the individual controls to 1.
This would make the controls take up the same amount of space on the screen. A sample xml is shown below.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:weightSum="2" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/hello_world">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Button" />
</TableRow>
</TableLayout>
</LinearLayout>
I've been trying to create what I think is a relatively simple layout for the past hour.
What I want is to have an edit text take up the vertical real estate left over after my buttons and labels are put onto the screen. I've found plenty of information on how to do that here at SO and I feel like I've implemented that information here (layout_weight and 0dip height), however as soon as I put in the 0dip height my edittext is just not displayed.
What am I missing here?
Edit: Turns out that my Layout2 was set to match_parent and this leaves 0 available space for the weighted children to occupy. I changed the behavior there to wrap_content and all worked great.
I'm targeting Android 2.3.3
Here's my layout xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/description"
android:textAppearance="?android:attr/textAppearanceSmall" />
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="0dip"
android:inputType="textMultiLine"
android:layout_weight="1" >
<requestFocus />
</EditText>
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/save" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/clear" />
</LinearLayout>
</LinearLayout>
because linearLayout2 fills out the parent. linearLayout2 must have layout_weight behaviour or own height not match_parent.
I have two LinearLayouts in my Android application. One (the top) holds a TextView and a Button and the one below it holds two buttons. I was wondering if there was a way to make the right button of the upper LinearLayout the same size as the right button of the bottom LinearLayout.
<LinearLayout android:layout_width="fill_parent"
android:id="#+id/linearLayout1" android:layout_height="wrap_content"
android:orientation="horizontal" android:paddingTop="15.0dip">
<TextView
android:paddingLeft="5.0dip"
android:textSize="33px"
android:textStyle="bold"
android:layout_height="wrap_content"
android:id="#+id/textViewPoints"
android:text="Points: 0"
android:layout_width="wrap_content"
android:layout_gravity="center_vertical"
android:paddingRight="25.0dip"
android:layout_weight="0" />
<Button
android:enabled="false"
android:onClick="myClickHandler"
android:layout_height="wrap_content"
android:id="#+id/buttonAddTracker"
android:layout_width="fill_parent"
android:layout_gravity="center_vertical"
android:text="#string/buttonAddTracker"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:id="#+id/linearLayout2" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingTop="15.0dip">
<Button
android:text="Calculate"
android:id="#+id/button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="myClickHandler" />
<Button
android:text="Reset"
android:id="#+id/button02"
android:layout_toRightOf="#+id/button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="myClickHandler"></Button>
</LinearLayout>
Well there are two ways how you can do that ...
1) If you are using Linear Layout as you are, then you'll have to fix the WIDTH of the Left TextView and Left Button then can't be wrap content , just give them say 40 dip . After that put Right Buttons Width to fill_parent or fix a WIDTH for them too .
2) Use TableLayout and put each of them in their respective columns and rows and the TableLayout should handle it for you.
